Low viscous cosmetic composition using a natural emulsifying agent

Abstract

The present invention relates to a low-viscosity cosmetic composition using a natural emulsifying agent. More specifically, the present invention relates to a cosmetic composition using a naturally derived saccharide-based surfactant in place of a chemical surfactant and realizing a low-viscosity formulation to offer safety to the skin, feel good on the skin with fast absorption, give stability to the formulation and add luster to the skin in an effective manner.

1 . A cosmetic composition comprising a mixture of a first saccharide-based surfactant having a first hydrophilic portion and a second saccharide-based surfactant having a second hydrophilic portion, the first hydrophilic portion of the first saccharide-based surfactant being more hydrophilic than the second hydrophilic portion of the second saccharide-based surfactant; and a natural oil-soluble ingredient, wherein
 the composition contains the mixture of the first saccharide-based surfactant and the second saccharide-based surfactant in an amount of 0.20 wt. % to 1.50 wt. % with respect to the total weght or the composition.   
     
     
         2 . The cosmetic composition as claimed in  claim 1 , wherein the composition is an oil-in-water type composition. 
     
     
         3 . The cosmetic composition as claimed in  claim 1 , wherein the composition has a viscosity of 1,000 to 4,000 cps. 
     
     
         4 . The cosmetic composition as claimed in  claim 1 , wherein the first saccharide-based surfactant includes at least one selected from the group consisting of polyglyceryl-3-methyl glucose distearate and inulin lauryl carbamate. 
     
     
         5 . The cosmetic composition as claimed in  claim 1 , wherein the second saccharide-based surfactant includes at least one selected from the group consisting of sucrose fatty acid ester, cetearyl glucoside, arachidyl glucoside, and C12-20 alkylglucoside. 
     
     
         6 . The cosmetic composition as claimed in  claim 1 , wherein the second saccharide-based surfactant and the first saccharide-based surfactant are used at a weight ratio of 0.4 to 2.5 
     
     
         7 . (canceled) 
     
     
         8 . The cosmetic composition as claimed in  claim 1 , wherein the natural oil-soluble ingredient comprises:
 a solid oil-soluble ingredient including a surfactant having a melting temperature of 30° C. or above and being in the solid state at the room temperature, said solid oil-soluble ingredient comprising a fat, a wax, a higher alcohol, a higher fatty acid, or a hydrocarbon; or   a liquid oil-soluble ingredient including an oil, an ester, or a hydrocarbon.   
     
     
         9 . The cosmetic composition as claimed in  claim 1 , wherein the cosmetic composition contains the natural oil-soluble ingredient in an amount of 5 wt. % to 15 wt. % with respect to the total weight of the composition. 
     
     
         10 . The cosmetic composition as claimed in  claim 1 , wherein the composition further comprises at least one ingredient selected from green tea polysaccharide, mushroom-derived yeast extract, and niacinamide. 
     
     
         11 . The cosmetic composition as claimed in  claim 10 , wherein the composition contains the green tea polysaccharide and the mushroom-derived yeast extract each at an amount of 0.01 wt. % to 5.0 wt. % with respect to the total weight of the composition. 
     
     
         12 . The cosmetic composition as claimed in  claim 10 , wherein the composition contains the niacinamide at an amount of 2 wt. % with respect to the total weight of the composition. 
     
     
         13 . The cosmetic composition as claimed in  claim 1 , wherein the composition is for improving skin luster. 
     
     
         14 . The cosmetic composition as claimed in  claim 10 , wherein the composition is for whitening the skin.
